Generate dialog result from a custom message box class

I am developing a custom messagebox class like the following-

Public Class MyCustomMsgBox


    Private MyForm As Form = New Form
    Private lblHeadline As Label = New Label
    Private lblMessageBody As Label = New Label
    Private btnNo As Button = New Button
    Private btnOk As Button = New Button
    Private btnYes As Button = New Button

    Public Sub New(ByVal Message As String)
        With MyForm
            .Width = 438
            .Height = 214
            .Controls.AddRange(New Control() {lblHeadline, lblMessageBody, btnNo, btnYes, btnOk})
        End With
    End Sub

    Public Shared Function ShowErrorMsg(ByVal ErrorMessage As String) As     Windows.Forms.DialogResult
        Dim obj As MyCustomMsgBox = New MyCustomMsgBox(ErrorMessage)
        obj.MyForm.ShowDialog()
    End Sub

    Public Shared function ShowSuccessMsg(ByVal SuccessMessage As String) As     Windows.Forms.DialogResult
       'some code
    End Sub

    P开发者_运维百科ublic Shared Function AskQuestions(ByVal Questions As String) As Windows.Forms.DialogResult
       'some code
    End Sub

    Public Shared Function ShowExceptions(ByVal ExMessage As String) As Windows.Forms.DialogResult
       'some code
    End Sub


    'Private Sub btnNo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNo.Click
    '  Windows.Forms.DialogResult.No()
    'End Sub

    End Class

Those functions are designed with related graphics, color, title and heading.

btnOk will return DialogResult.Ok, btnNo will return DialogResult.No and btnYes will return DialogResult.Yes

How do i return the dialog result with those functions?

How do i know that which button is pressed?

i dont know how to handle a button click event in a formless class.

Would you give me the idea?

Thank you in advance.

Start with the easy one. You will have to manually wire-up the events by using the AddHandler and RemoveHandler keywords this

AddHandler btnNo.Click, AddressOf btnNo_Click

btnNo is the button object. The ".Click" is the event you want captured. The AddressOf gets a pointer to the function (basically, it tells the compiler where the function is. Think of it as a different type of "handles".)

You'll have to remvoe the handler when your done, by doing this.

RemoveHandler btnNo.Click, AddressOf btnNo_Click

To set the Dialog Results, the form must be called via ShowDialog. You Simple set the DialogResults property of the form. I'd do it in the form.closing event.

me.DialogResult = Windows.Forms.DialogResult.OK

Me.DialogResult = Windows.Forms.DialogResult.Abort
Me.Close()

and it will return result Abort
